Space is filled with countless stars, all of which radiate enormous amounts of heat. These stars are tens of thousands of times bigger than our own sun. Still, space is considered to be cold. Why is that? If there are so many hot burning...

An increase in Earths rotational speed could have various impacts on life: ranging from increased earthquakes and tsunamis to a shortening of the length of the day. People could be floating in central Africa while the polar ice might...

Hot air balloons rely on heat alone to keep them in the sky. How does this work? Physics - Energy And Radioactivity - Learning Points. Hot air rises in cool air because it is less dense. The hot air within a hot air balloon creates the...

Conduction, convection and radiation are all ways in which heat is transported. How does each work, and what are they useful for? Physics - Energy And Radioactivity - Learning Points. The three types of heat transport are conduction,...

We create an underwater volcano by placing a conical flask of hot coloured water in a tank of cold water. The hot coloured water rises through the cold, demonstrating convection. Physics - Energy And Radioactivity - Learning Points....

Dr. Forrester talks about thermal energy. She defines thermodynamics and talks about conduction, convection, and radiation. She also defines photovoltaic energy. She talks about solar power and then shows how to make a solar oven.

This video explores five fun facts about heat transfer.

Temperature sensors explained. How do temperature sensors work? In this video we learn the basics of how different temperature sensors work. We look at thermometers, thermocouples, thermistors and resistance temperature detectors RTD.<br/>

Conduction and Convection examines convection and conduction by defining and exploring scenarios in which each occurs.

An igloo is made of compressed snow. Compact hardened snow is a great insulator of heat because snow is nothing but semi-frozen water with roughly 95% trapped air. The air molecules trapped between the tiny ice crystals create air...

This video describes density differentiation between ocean surface currents and deep ocean currents, and how this difference affects global ocean current flow.

This video will explain how atmospheric circulation and global wind patterns affect the movement of air on the earth.

UCLA is full of amazing scientists! What do they all do? Well, pretty much everything you can imagine, but in this series we will meet as many of them as we can, one by one! Let's start with geophysicist Jon Aurnou. He studies fluid...
